If you're a defenseman, then pull a dave Andreychuk and skate as fast as you can forward, then pivot and glide backwards.

Always try to stay not as close as you normally would stay to a player, that way, if you do, and they try to speed up, you can react and get in their way, if they try to take a shot, it's ether going to be a weak one, or you can get in their way and block it, deflect it, or even steal it away.
